I’m using a SAMD21G18 microcontroller with Arduino as the development platform and I want to implement a UART interrupt service routine. Is there a way to achieve this?
Hi there,
Something like this would do.
void setup(){
Serial.begin(9600);
pinMode(7, INPUT); // Make pin 7 RXD an input
// attach our interrupt pin to it's ISR
attachInterrupt(0, recISR, CHANGE);
// we need to call this to enable interrupts
interrupts();
}
// The interrupt hardware calls this when we hit our left bumper
void recISR(){
// rec = 1;
Serial.println("interrupt!");
}
Give something like that a try.
